snow-WINDOW FASTENER.

T cell whom it ma'y concern:

-Be it known that I, GE'OR'GE C. MARR, a

citizen ofthe United States, residing at.

Washington, the District of Columbia,

have invented certain new and useful Improvements 1n Show-VVmdowFasteners; and

I do declare the following to .be a full, clear,

and exact description of the invention, such as Wlll enable othersskilled in the art to this specification.

My ijventlon' relates to a class of show cases, but more particularly toa show win dow fastener, and has for its object to provide a '-fasteningmeans for the contiguous edgesof platesof glass, which fastening doesnot-require the inside edges of the glass-to be polished or beveled.

Afurther object of my invention is to pro- .vide a fastener which willto a great extent protect the glass from breakage, and which will holdthe selvage and prevent same from falling should the glass beaccidentally broken.

A further object of my invention is to provide a postfandfastener whichwill provide for wiring electric lights in the front corners of thewindow. I

A further object of my invention 1s to provide a post and fastener soarranged and constructed' that the distance between the fasteners,clamps or anchors can be regulated to suit the character of the work,the fasteners or clamps. being longitudinally movable or adjustablewithin the post arid not permanently connected thereto.

A further obj eot of my invention is to provide certain improve cuts inthe construction and arrangement of parts over the S. patent granted tomeon May 28, 1907,- No. 855 195.

With these objects in view my invention consists in the novel =1;rangement and construction of the post and clamping means.

My invention further cons sts in the novel arrangement providing for ametal tube or .pipe acting as a conduit for electric wiring.

My invention further consists in the combination of the movable oradjustable clamp 01' anchor and the associated clamping parts. This postand. fastener is constructed with a View to being employedwhere an excepSpecification of Letters Patent.

t'ionally heavy, stout and rigid fastener is re-' quired, and is alsodesigned to be employed inall instances-where the inside corners of theglass is to present a particular neat and finished appearance, such-asis of'co'ursede sirable .whenever windows are equipped with cornerlights. i

Referring to the accompanying drawings: Figure 1 is a perspectiveviewshowing two plates of glass and illustrating the post and fastener inoperative position. Fig. 2 .is a

perspective view taken through the outside corner of the post andfastener, and, Fig. 3 is a horizontal sectional View through the same.

.Like numerals of reference indicate the same parts throughout theseveral figures'in which: I lindicates the plates of glass. I 4 2indicates the outer post, said post 2 comprising a'curvecl portion 3',which as shown in Fig. 3 "is substantially semicircular in cross sectionhaving the edges 4 and 5' thereof turned inwardly at an angle to eachother of substantially 90 degrees .(this assuming that the two pieces ofglass. to be fastened" are at right angles to each other).

6 indicates the post clamp or anchor which, as shown in Fig. 3, has itstwo ends 7 bent or curved'in the direction of the curve or are of thecurved post 3, while the said post clam or anchor 6 is providedcentrallywith a bo t 8, said bolt being either formed integral with theclamp or anchor 6, orsecured thereto in any convenient manner. The bolt8 has its inner end threaded at9 to, accommodate a nut or tap 10 asclearly shown in Fig. 3.

11 and 12 indicate the two side plates whichare secured to the curvedpost 3 and which together therewith form the outer 'p ost 2, said plates11 and 12 extend a considerable distance beyond the ends of the curvedpost 3 as clearly shown in Figs. 2 and 3, and being designed to beconstructed of polished metal. This arrangement presents aparticular'striking appearance and at the same tim'e provides a corner post ofexceptional strength and rigidity. As shown in the drawings the sideplates 11 and 12 overlap the edges of the glass plates 1.

In order to insure a perfectly tight and strong construction and inorder to space the glass plates 1 uniformly their height I provide an.angular post 13 against which the extreme edges of the glass plates 1abut as clearly shown in the drawings, the bolt 8 of the clamp or anchor6 passing through said post 13 centering the same and preventing anymovement thereof.

14 indicates the inner post which may be constructed of Wood or othersuitable material, said post being provided with a depression 1.5 andperforated to receive the bolt 8 and the nut or tap 10. The sides of theinner post 14 are formed at substantially an angle of 90 degrees toaccommodate an angle bar 16' on each side, the outer portion of eachangle bar 16'being in engagement with the inner surface of the glassplates 1, while the inner portion of each angle bar 16 extends inwardlyover the post 14 completely covering the same. As shown in Fig. 3 thepost 14 is provided with a longitudinal annular groove or recess 17 toaccommodate a metal pipe or tube 18 which serves as a conduit for anelectric wiring 19; and it is my intention to arrange the angle bars 16and the tube or pipe 18 in such manner that the inner edges of the anglebars 16 engage the pipe or tube 18 to hold the said pipe-or tube inposi-- tion within the annular groove or recess 1? at the same timeallowing said plpe or tube 18 to be rotated for the purpose of swingingthe lamp or lamps secured thereto toward one glass or the other. Thisarrangement is desirable in show windows where it is desired tobrilliantly display any particular article or articles.

As shown in Figs. 1 and 2 an electric bulb 20 arranged on a bracket 21of suitable design is carried on the rotatable tube or pipe 18, theelectric wiring 19 entering said bracket and thus leading to the bulb;all wiring'being invisible.

Having thus fully described my invention its operation is obvious.

In order to secure or fasten the contiguous edges of two plates of glassthe post 13 is bored or perforated at desired intervals in order toaccommodate any number of clamps or anchors 6, the inner post 14 beingalso bored or perforated to register with the perforations in the post13. Where any particular strength or rigidity is required any number ofclamps oranchors 6 can be employed as said clamps or anchors arelongitudinally movable -0r adjustable ,within the curved post 3.] Theinner post 14:,angle bars 16 and conduit pipe or tube 18 are thenassembled as shown in Fig. 3.

Having thus fully described my invention what I claim as new and desire,to secure by Letters Patent of the United. States, is:

A device-for securing and clamping together the contiguous edges ofplates of glass, comprising a curved post, a side late under each edgeof said curved post, a'c amp or anchor within said curved post, a boltcarried on said clamp or anchor, a post unders'aid side plates forspacing apart the plates of
